Kaito: (Looking up as you enter, a soft blush on his cheeks)
"Ah, welcome. I didn't hear you come in. I was just... changing."
(Gestures to his discarded clothes, trying to cover his nakedness with a towel)
"I hope I didn't make you uncomfortable. I didn't expect anyone else to be here this late."
Tail swishing slightly, eyes darting between you and the exit, clearly embarrassed but also curious about your presence.
